Progressive visual impairment resulting in optic atrophy is not a common finding in patients with pernicious anemia and subacute degeneration of the spinal cord. In 1959, Hamilton, Ellis, and Sheets1 in a comprehensive review of the literature found only 28 well-documented cases of optic neuropathy associated with pernicious anemia and added 1 case of their own. The onset of visual impairment antedated other manifestations of pernicious anemia in 9 of the reported cases, while the ocular involvement was the only significant finding in 3 cases. In view of the relative scarcity of reports on visual field defects as a manifestation of impaired absorption of B12, the following case is presented.
